I'm not 100% on whether ndo_set_multicast_list can be NULL after this
or not. If ndo_set_rx_mode is set everything _should_ be using it.

dma_map_sg could return a value different to 'nents' argument of
dma_map_sg so the ide stack needs to save it for the later usage
(e.g. for_each_sg).
The ide stack also needs to save the original sg_nents value for
pci_unmap_sg.

Samsung DB-P70 somehow botched the first ICH9 SATA port. The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.
Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely. Fortunately, the controller does
have subsystem vendor and ID set. It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

libata keeps a shadow copy of the ATA CTL register (which is write only),
and only writes to the hardware when the required value doesn't match
the shadow. However this copy wasn't being maintained when performing
reset functions. This could cause problems for the first operation after
a reset when the correct value might not be written to the CTL register.
This problem was observed when hotplugging a drive: the identify command
was being issued with interrupts enabled, when they should have been
disabled.

driver core: move klist_children into private structure
Broke our parisc build pretty badly because we touch the klists directly
in three cases (AGP, SBA and GSC). Although GregKH will revert this
patch, there's no reason we should be using the iterators directly, we
can just move to the standard device_for_each_child() API.

Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block
device driver.
The ps3vram driver exposes unused video RAM on the PS3 as a block device
suitable for storage or swap. Fast data transfer is achieved using a local
cache in system RAM and DMA transfers via the GPU.
The new driver is ca. 50% faster for reading, and ca. 10% for writing.

Guennadi Liakhovetski noticed that the end condition for the loop in
bitmap_find_free_region() is wrong, and the "return if error" was also
using the wrong conditional that would only trigger if the bitmap was an
exact multiple of the allocation size, which is not necessarily the case
with dma_alloc_from_coherent().
Such a failure would end up in bitmap_find_free_region() accessing
beyond the end of the bitmap.

A long time ago, xs->base is allocated a 4K size and all the contents
in the bucket are copied to the it. Now we use ocfs2_xattr_bucket to
abstract xattr bucket and xs->base is initialized to the start of the
bu_bhs[0]. So xs->base + offset will overflow when the value root is
stored outside the first block.
Then why we can survive the xattr test by now? It is because we always
read the bucket contiguously now and kernel mm allocate continguous
memory for us. We are lucky, but we should fix it. So just get the
right value root as other callers do.

STag zero is a special STag that allows consumers to access any bus
address without registering memory. The nes driver unfortunately
allows STag zero to be used even with QPs created by unprivileged
userspace consumers, which means that any process with direct verbs
access to the nes device can read and write any memory accessible to
the underlying PCI device (usually any memory in the system). Such
access is usually given for cluster software such as MPI to use, so
this is a local privilege escalation bug on most systems running this
driver.
The driver was using STag zero to receive the last streaming mode
data; to allow STag zero to be disabled for unprivileged QPs, the
driver now registers a special MR for this data.
